The top executive at Cambridge University got a soaking as he accepted Prof Stephen Hawking's nomination for the Ice Bucket Challenge.

Prof Sir Leszek Borysiewicz, the university's Vice-Chancellor, is the latest public figure to have ice cold water tipped over him for the charity craze sweeping the nation.

Suited and booted in a video posted online by the university he said: "I am pleased, I suppose, to be doing the Ice Bucket Challenge on behalf of Motor Neurone Disease Association and I thank Stephen Hawking for my nomination for this particular challenge.

"In my turn I nominate Ian Farrar, the chief executive of the Wellcome Trust, also John Savill, chief executive of the Medical Research Council and Hugh Pelham, chief executive of the MRC Molecular Biology Laboratory here in Cambridge."
